Of course Ariad's '113 works 10 x better than Pfizer's crizotinib. Of course it does because it's in a petri dish on xenographs. Ariad has "bragging rights" on their petri dish product until they actually get it into a single human being (around mid-2011). So, don't expect to see any FDA approval from '113 until 2014 (earliest).
Essentially vapor-ware until they get it into a human being.
